COMPLEMENTARY METAL-OXIDE SEMICONDUCTOR IMAGE SENSOR HAVING SMALL SIZE OPTICAL BLACK AREA

摘要

A CMOS(Complementary Metal-Oxide Semiconductor) image sensor for reducing size of an optical black area is provided to reduce whole area of the CMOS image sensor by reducing the size of the optical black area. An active pixel array(110) includes a plurality of active pixel rows each of which includes a plurality of active pixels. An optical black area(120) includes one optical black pixel row which includes one or more optical black pixels. A video signal processing part(140) removes offsets of video signals outputted from the active pixel rows based on an optical black signal outputted from the optical black pixel row, and generates corrected video signals. The video signal processing part uses the optical black signal in order to remove the offsets of the video signals outputted from the active pixel rows.
